Catenary Model Designs for Streetcars in Norway
Customer Project
The Infrastructure department of SDEA Engineering Solutions has extensive experience in the railroad sector, especially in designing electrification using overhead contact lines (OCS/OLE), where it has developed projects for high-speed trains in England and streetcar lines in Norway.

Model
In projects for streetcars, the overhead catenary designs lead to elements with highly non-linear behavior, with large deformations that require correct structural analysis so as not to put the line out of service.
After an exhaustive comparison of the software packages on the market, SDEA Engineering Solutions found the answer it needed in Dlubal’s RFEM software. This program has a very good learning curve (as easy to handle as an Excel sheet), a large number of tutorials, and extensive ad hoc documentation. In addition, its team of technicians deserves special mention, as they worked hard to solve all the questions that arose during the initial phases of the project.
From a technical point of view, the option of creating fully parameterized models was essential, from the geometry, to the loads, to the final result output. Another fundamental point was the software's intuitive and agile menu for defining action combinations and the fact that many of them were predefined, based on the most relevant standards of a wide variety of countries.

Section Classification in RFEM 6 According to EN 1993-1-1
The design of cross-sections according to Eurocode 3 is based on the classification of the cross-section to be designed in terms of classes determined by the standard. This article will show the section classification in RFEM 6.

Application of Connections to the Structure | Steel Joints
- The proposed connection can be applied to all selected nodes in the structure
- The location of the connection can be defined using the "Main" tab of the Add-on dialog box
- The design is performed for all connections in the structure and after the calculation, the results on all connections can be displayed
- The table shows the results for the individual connections, each connection is designed and can be saved separately

The limit stress is activated, but my stress ratio is “non-designable” in the Stress-Strain Analysis add-on. What could be the reason?
- How do I define effective lengths when designing steel members in RFEM 6?
- I have trouble with design of a steel structure. For a singly symmetric cross-section (UPE), the program cannot perform the stability analysis. It reports that the Equivalent Member Method 6.3.3 is not applicable for an unsymmetrical cross-section. Is it possible to design such cross-sections in the program?
- I would like to export nodal support forces of several load cases, load combinations and result combinations into an Excel spreadsheet in RFEM 6. How should I proceed?
- How do I create a user-defined Design Situation with my own chosen load combinations?
- I cannot analyze a UPN cross-section subjected to a double bending in the program. Is it possible to do this in the program?
- How do I perform stability analysis to determine the critical load factor in RFEM 6?
- How can I optimize cross-sections within the steel design?
- Where can I find the materials for the corresponding National Annexes in RFEM 6 and RSTAB 9?
- How do I define effective lengths when designing steel members in RFEM 6?
